Title: Constant current circuit
Inventor: KATOU MITSUHARU
IPC: G05F1/56
Filed: 1981-06-09
Abstract: PURPOSE:To obtain a constant current with stable operation simply, by setting an offset voltage to a differential amplifier and comparing a potential difference generated across a current detecting resistor. CONSTITUTION:An MOS transistor TR12 for voltage controlling and a registor 13 for current detection are connected in series with an input terminal 11 and another end of the resistor 13 is grounded, where a current flowing to a point C and a point A is represented respectively as IA and IC, Rs represent a resistance value of the resistor 13, and potentials across the resistor 13 are represented respectively as VA and VB. When a voltage Vc at a point C is increased, the current Ic is increased and since the resistance value Rs of the resistor 13 is constant, the potential difference VA-VB>1 is obtained. Thus, an output voltage VD of an amplifier 14 goes to L level to increase the impedance of the TR12 and to decrease the current IC. Inversely, when the voltage VC drops, VA-VB<1 is obtained, the impedance of the TR12 is lowered, and the current IC is increased. Thus, the constant current control can be exercised.

Title: Error detecting system for magnetic disk
Inventor: SHIROKABE TAKU
IPC: G11B20/18
Filed: 1990-04-03
Abstract: PURPOSE:To improve efficiency for inspection by switching the control voltage of an AGC amplifier in a certifier to whether AGC is loaded or fixed according to the error class of a test signal. CONSTITUTION:An amplifier 7a of a sample/hold circuit 7 samples the voltage of an AGC voltage generation circuit 2 to follow up the amplitude fluctuation of the test signal from a disk to be inspected. When detecting MIS error, the voltage is passed through a switch 7b, held at a capacitor 7c and supplied through an amplifier 7d to an AGC amplifier 3. When finishing MIS error detection to one track, the switch 7b is opened and the final AGC voltage held at the capacitor 7c is supplied as the control voltage of the amplifier 3. Then MOD error is detected. Next, the test signal is erased and EXT error is detected while maintaining the control voltage as it is. Thus, when one track is inspected, the required rotation is shortened from 8 to 6.

Title: Logic circuit design system
Inventor: HAYASHI MORIHIKO
IPC: G06F17/50
Filed: 1990-04-05
Abstract: PURPOSE:To finally obtain a logic circuit at a correctly connected physical level despite the evolution carried out for the functions which are not corresponding to each other in 1:1 by generating the new circuit connection information after evolving the connection relation within an evolved circuit function based on this function every time the evolvable circuit function is evolved based on the knowledge stored previously. CONSTITUTION:The input/output connection information is repetitively updated in response to the evolution of the evolvable circuit function until all circuit functions are evolved at the physical levels every time the circuit function is successively analyzed toward a physical level from a higher rank circuit function level based on the design specifications given from outside and the knowledge stored previously. In such a way, a circuit and the connection information are evolved separately from each other when the circuit is evolved with the start of a rule. Thus the circuit function is evolved in consideration of the connection relation not only to the block to be evolved but to other circuits. Then the hierarchical design is easily attained via a computer.

Title: Chatacter recognizing method
Inventor: OSHIRO MUNEHIRO
IPC: G06V30/144
Filed: 1993-03-24
Abstract: PURPOSE:To provide a character recognizing method which can simply recognize the handwritten numeric characters by means of an image processor. CONSTITUTION:A recognition pattern consists of windows (1)-(7) of a prescribed shape which are set each intermediate position of 7 segments forming a shape that connect together the middle points of both longer sides of a rectangle. Thus numeric characters 0-9 are defined by combinations of those windows. For instance, the numeric character 1 is defined by windows (2) and (3), and the numeric character 7 is defined by windows (1), (2) and (3) respectively. Meanwhile a guide pattern of each window combination shape is printed on a form as a target of description, and the point of description is decided by each definition. When the numeric character 1 is described, for example, two serial segments where the windows (2) and (3) are formed are used as the targets of description. The recognition pattern is put on each character for detection of the presence or absence of the line element of each window. If the line elements are included in the windows (2) and (3) only, it is decided that the numeric character 1 is described. Thus the handwritten numeric characters can be accurately recognized despite the variance of description.

Abstract: PURPOSE: To enable switching to backup control without giving external disturbance to process, by outputting the output of computer control to the backup control at the same time, in case of ratio control by the computer.  
     CONSTITUTION: The process control section 21 outputs the signal 102a to the ratio control section 30 and outputs the same operation signal 102b to the converter 22. The unit 22 converts the digital signal 102b into the whole flow rate set signal 104 and at the same time supplies the same output for setting the initial value of the process control unit 23. Further, the control units CN1...CN3 read in the set output to the flow rate control units FCa...FCc in computer control as the reference input and read in the output of the ratio set units 4...6 as the process input and output the ratio set value so that the difference of the both is zero. Thus, the ratio of the set units 4...6 is always in accordance with the ratio set by the control section 30 and switching to backup control is made possible without giving external disturbance to the process.
